Instead of focusing on how many backlinks you have, focus on how to build up more :) Instead of spending your days tracking your link popularity and worrying that it isn't high enough ... Be proactive!
Don't be a student taking a test and focusing on time slipping away on the clock instead of the work needed to succeed!
A backlink analyzer using Google would be completely useless imho, for a few main reasons:
1. goog only shows links pointing to a single page, not an entire site
2. goog only updates the links they decide to show whenever they feel like it
3. goog's link command seems to show a random sample of links, wheras yahoos linkdomain is much more comprehensive

Anyone can very simply use the appropriate command within each search engine to gather a list of backlinks. What Aaron's utility does it actually manipulate the data received by the search engine APIs. In other words, if Google were included (hypothetically), it would fetch a link:[url]www.site.com[/url] where it would be returned a list of pages. The script would then determine how many unique domains are contained within the list, and the number of pages per domain. So, for example, if I were to do it to www.mysite.com, it would return:
and so on and so forth. For how popular doing a link: in Google is, I'm sure you can see the value of having the results returned sorted and categorized. It's actually pretty easy to code thanks to Google's amazingly simple API. I would actually write the script myself if it weren't for the fact that I'm amazingly lazy and have other things to do. :)
